Several methods for controlling water flow in submersible pumpsMay 08, 2017

1. Variable speed regulation. Changing the speed of submersible pump can change the performance of the pump, so that the pump's operating conditions change, this method is called variable speed mediation.

2. Variable diameter adjustment. After turning the impeller, the pump performance will change according to certain regularity, so that the pump working conditions change, we turn the impeller to change the water pump operating point of the method, called variable diameter adjustment.

3. Variable angle adjustment. Changing the angle of the blade installation can make the pump performance change, so as to achieve the purpose of changing the operating conditions of submersible pump, the way of changing the working point is called the variable angle adjustment of the pump.

4. Throttling adjustment. For the water pump installation of outlet pipe, the gate valve is shut down and the local resistance is increased in the pipeline, and the piping characteristic curves are steeper. Its operating point of the water pump along the Q-H curve to the left, the lower the gate valve shut, the greater the resistance, the smaller the flow becomes, this way through the closing of the small gate valve to change the pump operating conditions, called throttling or variable valve regulation.
